Rihanna shut down the Met Gala carpet Monday encased in white camellias on a jacket with a long train gown. Janelle Monae dropped a bulky coat to reveal a see-through cage and Jeremy Pope walked in a 32-foot cape emblazoned with the visage of Karl Lagerfeld.

In the spirit of Lagerfeld himself (he was not often on time), Rihanna and her Valentino couture had the carpet to themselves save her partner, A$AP Rocky, who wore a red tartan skirt over crystal-studded jeans with a train of his own. They showed up well past everyone else.

Around her neck was a short Bulgari necklace in Akoya cultured pearls and pearl-shaped diamonds.

Lagerfeld was the honoree at the A-list gala with many in the crowd of about 400 dressed in vintage looks from the fashion houses where he worked during a career of more than 60 years.

But elegant wasn害羞草研究所檛 entirely the hallmark of the evening. Jared Leto dressed as Choupette, Lagerfeld害羞草研究所檚 beloved fluffy cat. Lil Nas X went full cat covered in crystals by Pat McGrath and Dior Men.

Bad Bunny showed up late in bright white from head to toe with a long cape also adorned with camellias, a Coco Chanel motif embraced by Lagerfeld. Monae害羞草研究所檚 look, with a black sparkly leotard underneath, was made by Thom Browne.

Cardi B first donned pink then switched to a full black ballgown with, you guessed it, camellias. Up top, she said, 害羞草研究所渋s giving Karl, the house of Chanel and Karl at the same time.害羞草研究所� It was a men害羞草研究所檚 white collar shirt accent with a black men害羞草研究所檚 tie. The outfit in honor of Lagerfeld was done by an up-and-coming British design house, Chenpeng Studio.

害羞草研究所淭he Met Gala dress code was `in honor of Karl害羞草研究所� and guests definitely understood the assignment,害羞草研究所� said Alison Cohn, deputy fashion news editor for Harper害羞草研究所檚 Bazaar. 害羞草研究所淭hey referenced the many signatures Karl Lagerfeld developed over his six-decade plus career.害羞草研究所�

Many used boucle fabric (Teyana Taylor害羞草研究所檚 Thom Browne suit and Anne Hathaway害羞草研究所檚 Versace safety pin number). Also adorned in camellias were Emily Blunt in a Michael Kors blouse and Adut Akech in a Carolina Herrera gown.

Dua Lipa walked in a white Chanel ballgown from the fashion house害羞草研究所檚 archive and Nicole Kidman chose a look Lagerfeld himself made for her 20 years ago.

And there were some bombshells: Serena Williams wore a flapper Gucci look when she announced she害羞草研究所檚 pregnant with her second child.

Lipa, a gala co-chair, wore a Tiffany & Co. diamond around her neck. She called her cream-colored dress, by Chanel from 1992, 害羞草研究所渧ery, very special害羞草研究所� as it has been on her mood boards.

Claudia Schiffer wore the gown on the runway for its debut, although hers had a matching hat. Lipa害羞草研究所檚 necklace in platinum included a center diamond of more than 200 carats.

Nicole Kidman said it was Lagerfeld who ignited her fashion spark. She wore a pale pink gown created by Lagerfeld for a Chanel No. 5 commercial she starred in. It害羞草研究所檚 adorned with 3,000 silver crystals for the ad directed by Baz Luhrmann.

害羞草研究所淚害羞草研究所檓 very grateful to wear it,害羞草研究所� she told The Associated Press. 害羞草研究所淗e was so much a part of my life, as were his whole team. He was the one really sort of shepherded me 害羞草研究所� in terms of my love of fashion.害羞草研究所�

Kidman topped off her look with Harry Winston diamonds.

害羞草研究所淢y favorite look was Nicole Kidman害羞草研究所檚 ethereal feathered sequin Chanel gown. Typically stars wear new couture straight off the runway or have a custom look commissioned. It was a lovely statement about sustainability, proving that beautifully hand-crafted pieces never go out of style,害羞草研究所� Cohn said.

Kim Kardashian, meanwhile, went with loops and loops of pearls all over her Schiaparelli look. And Cardi B went big in pink, complete with a feathery head piece. Brittney Griner wore a warm stone shade in a suit with a long jacket by Calvin Klein, who also dressed her wife, Cherelle Griner, in a sleek strapless column dress in white onyx.

Many in the crowd counted Lagerfeld as a friend or worked with him at Chanel, Fendi, Chloe or one of the other fashion houses where he created.

And many guests wore black to walk the unusual carpet in a line design. It was a color Lagerfeld wore almost exclusively. Black-and-white combos were also plentiful.

Kristen Stewart wore the color duo in a suit with a cropped white jacket. And Cara Delevingne honored her old friend Lagerfeld with a ruffled white shirt look short in front with a train at the back. Ruffled shirts were among Lagerfeld害羞草研究所檚 favorites.

The classic colors weren害羞草研究所檛 for Viola Davis. She walked in a stunning neon pink strapless gown with long feathers at the bodice.

Frenchye M. Harris, CEO and founder of the online fashion site The Black Fashion Movement had one word for Davis: 害羞草研究所淕orgeous!害羞草研究所�

She called Anne Hathaway害羞草研究所檚 Chanel-inspired but Versace-created look with the pins and camellias at the breast 害羞草研究所渟uper cool and a great marriage between the brands.害羞草研究所�

Gigi Hadid wore Givenchy in black with feathers, a drop waist and sheer train in tulle. It took more than 300 hours to make. Kendall Jenner was also in black, sans pants. She wore a sparkly leotard with long sleeves that has pieces doubling as a train. On her feet were kinky, towering black boots, all courtesy of Marc Jacobs.

Jenner害羞草研究所檚 high white collar was a nod to those worn by Lagerfeld. Her hair was in a high ponytail.

Rita Ora was also in black, a stunner of a peekaboo sheer look from Prabal Gurung. It was silk tulle with corset detailing and sexy draping in chiffon. One shoulder was dropped.

Margot Robbie, who stars in this summer害羞草研究所檚 害羞草研究所淏arbie害羞草研究所� live-action film, wore a 1993 Chanel gown in black that Cindy Crawford first wore on a runway. Robbie said she was the last Chanel ambassador to be handpicked by Lagerfeld.

害羞草研究所淚 feel really great in it. It害羞草研究所檚 an honor,害羞草研究所� she said.

The invitation-only gala earned $17.4 million last year for the museum害羞草研究所檚 Costume Institute, a self-funding department with a budget dependent on the gala害羞草研究所檚 success. The price of attending went up this year to $300,000 for a table and $50,000 for a single ticket.

The guests from fashion, film, music, theater, sports, tech and social media were asked to dress 害羞草研究所渋n honor of Karl害羞草研究所� by gala mastermind Anna Wintour, a close Lagerfeld friend who first signed on to the event in 1995 and took over the helm in 1999.

The party coincides with the Costume Institute害羞草研究所檚 blockbuster spring exhibition: 害羞草研究所淜arl Lagerfeld: A Line of Beauty.害羞草研究所�

American fashion was last year害羞草研究所檚 vibe. It followed gilded glamour and white tie. Camp was the theme in 2019, producing what is considered one of the wackiest displays of dress by the celebrity crowd.

Lagerfeld worked for Chanel, Fendi, Chloe, Jean Patou, Balmain, his own brand and more.

This year害羞草研究所檚 five hosts include Wintour, as usual, and also Michaela Coel, longtime Chanel ambassador Penelope Cruz, and recently retired tennis superstar Roger Federer.

Cruz looked like a bride with a sheer hood on her white Chanel belted gown with silver details from spring/summer couture collection in 1988.

Asked how he got to be a Met Gala co-chair, Federer said it helps to know Wintour. He said it makes sense for athletes to be at the gala because they害羞草研究所檝e become a bigger part of the fashion world in recent years.

害羞草研究所淚 think the sports people have gotten more and more fashionable,害羞草研究所� Federer told the AP. 害羞草研究所淲e害羞草研究所檙e fortunate to get onto covers much more frequently nowadays. Before it was always the models, the good-looking people, not the athletes.害羞草研究所�

Fendi, where Lagerfeld worked for more than 20 years, was also represented. Suki Waterhouse wore a 2019 Fendi design by Lagerfeld in silk tulle and delicate flowers and birds on sheer panels.

Lagerfeld害羞草研究所檚 cat, Choupette, had been rumored to attend but her humans posted on Instagram earlier in the day the 11-year-old feline was staying put in Paris. Doja Cat害羞草研究所檚 cat-eared hood on a sparkling white and silver-beaded dress was an ode by Oscar de la Renta. She wore prosthetics that gave her a feline face and claws.

Chloe Fineman carried a cat-shaped bag and Emma Chamberlain wore 害羞草研究所淐houpette blue,害羞草研究所� a light blue hue created by Lagerfeld. James Corden also showed up in the shade.

As for Leto, he swapped out his cat costume for a black caped look.
